Hi Craig - taping can be good for training, but make sure you take it off in between training sessions to allow the toe to get it's normal movement back and prevent it from stiffening up.

Mobilising the joint can also help - try to gently move the toe around to regain as much movement as possible. As it improves, you can throw in some strengthening exercises and balance work. If you know a good sports physio / osteopath, a one off session may help to get you pointed in the right direction.
